Id polymer composites for medical application

The work concerns ID composites with resorbable polymer (poly-UDL-laetidc) matrix which can be used as medical implants. Composites were reinforced with three types of long fibers such as carbon, polyacrylonitrile, and alginate. The samples were produced in two-stages process: composite films casting and hot press moulding. Obtained paddles were incubated in distilled water. Mechanical properties (tensile strength, Young modulus) of the samples before and after different incubation time were measured. On the basis of pH and conductivity changes of water during compositcs incubation the degradation rate was investigated. Additionally the morphology of the surface were evaluated. The composites significantly differed in mechanical properties and degradation rate.
